To all whom it may concern.'

. Be it known that I, DANIEL C. GIDLEY,

of Albany, in the county of Albany and State of New York, have inventeda certain new and useful Electric-Conduit Fitting, of

which the following is a specification.

' 'My invention has for its object the production of lan eljectricconduit fitting by y which the electrical appliance `supported j therebycan be adjusted axially and easily adapted to different conditions andthicknesses` of Walls concealing Athe conduit' workz-and it consists inthe 'combinations and constructions hereinafter set forth and claimed. jIn describing this invention, reference is hadl to the accompanyingdrawing in which like 'characters' designate corresponding parts in allthe views.'

Figure l-is an elevation, partly' broken away,l of a preferableembodiment of my invention, the contiguous portions of the wall in whichthe fitting is embedded being also shown in section. Fig. 2 is a topplan of this fitting, partly broken away, and

. and havinga' flat bottom 2 and an opening 3 in its wall opposite thebottom, and also one or more internally threaded nipples 4 adapted to beconnected to the conduits which inclose the electric wires.

4The opening 3 i's closed by a cap comprising inner Aandy outertelescoping sleeve members 5;, 6, one being fixed to the body 1 and theother being adjustable axially of the fixed member. In this embodimentof my invention, the outer sleeve member is fixed and the inner memberadjustable, and

the outer member is provided with an external annular `iiange 7 whichrests upon the margin 8. of the wall of the body around the opening 3,and is 'secured thereto by screws 9 extending through said iiange andinto lugs 10 provided on said margin 8. v Usually, the outer edge of themarginl 8 isformed with an inwardly extending lip 11 which engages theinner face of the fiange 7, and the flange 7 is formed with a lip.12

Vat its outer v'edge which engages the outer face of ,the margin 8. Thismode of connecting the body and the outer sleeve member forms a tightjoint, and [dispenses with the necessity of machine inishing'liatsurfaces of the iange 7 and wall 8.

The adjustable inner sleeve member 6 is held in its adjusted position byclamping means, as screws 13, extending through spiral slots 14 formedin the outer sleeve member, the screws 13 threading into the innersleeve member. Obviously, by loosening the screws 13 and turning theinner sleeve member, the screws'will pass along the slots from high tolow points thereof, or vice versa, and thus arrange the inner sleevemember either farther into or out of the outer sleeve member. The outersleeve member 5 may be provided with butone of -these slots, but-inorder to more iirmly support the inner sleevemembcr 6, the outer member5 is usually provided with three of such slots. The inner sleeve member6 is also provided with an inturned flange 15 at its outer end for apurpose to be presently explained.

- 16 is a socket for an electrical appliance, as a lamp7 said socketextending into the inner sleeve member 6 and having terminals 17, 18 atits inner endfor connection with the wires within the body. The socketis also provided with the usual central and l' sleeve terminals whichengage the terminals' 90 of the electrical appliance.

The cap is constructed to receive sockets of standard makes and sizesand all of such sockets usually are provided at their outer ends withexterior annular flanges, as the flange 19, which laps upon the inturnediiange 15 of the inner sleeve member 6 and is secured thereto by screws20. The periphery of this flange is of less diameter than the interiorof the outer sleeve member 5Aso that it may, if necessary extend partlywithin said outer sleeve member.

In some instances, especially in concrete buildings, the conduits andfittings are embedded in the walls, as illustrated in Fig. 1, and thedistances vary at which the conduits and the bodies of the ittings arelocated below the surface of the walls, and in use, by adjusting theinner sleeve member axivarranged close-to the plane of the outer InConcrete walls, the sleeve (i is adjusted to come flush with, -or inproper relation to, the shorings which confine the concrete until ithai-dens.

Although niy invention is particularly applicable for use in 'connectionwith concealed conduit work, obviously-conditions may arise in which itmay be uscdbadvanl tageously in exposed or other forms of work.

What I claim is` 1. In an electrical appliance, the combination with ahollow body having an opening in one side thereof and a bearing sur-eface on the outer face ofthe margin of 4the wall around said opening,the extreme'edge of said margin being turned outwardly forming a lip, a,sleeve arranged coaxially with said. 'opening and provided with a baseflange overlying said margin and having an overturned edge resting onsaid bearing surface, the lip on said margin projectf f l of said marginbeing,r turned outwardlyl forming a lip, a sleeve arranged coaxiallywith said opening` and provided with. abase fiange overlying said marginand having an overturned edge resting on said bearing surface, the lipon said margin projecting to` ward said liange, means for attaching saidange to the side of the body, a second sleeve adjustably supportedwithin the former sleeve, and an electrical appliance carried by thelsecond sleeve, substantially as and for'the purpose sp cified.

In testimony whereof, I have hereunto signed myname, in, the presence oftwo attesting witnesses, at Syracuse, ini the county of Onondaga andState of New York, this 5th day of October, 1910.
